Lost cam
I lost my cam at start up it is a very mild 383 with a L82 cam so now do I try flush engine in car or do I remove the motor for a complete tear down. I hope I can flush it in the car. All my work for the last month down the drain.

Unless the cam bearings are coppered bad/oil pressure low change the cam. Guess you can flush it?
take the manifold off , drain plug out and dump some diesel in there. Turning the oil pump may/may not help
Not saying its the milliionaire solution but done changed bad ones plenty of times w/no flushing it ran for years.

Sorry to hear about the cam. I would make sure to use an oil filter mount that has the bypass valve blocked and an oil filter without a bypass at least for the first and second oil change. Easy and cheap protection. If you really want to keep the oil filter bypass function, you can easily swap it out for a stock oil filter mount later. Just 2 bolts.

This has come up quite a few times over the years but I have put new cams in after wiping a lobe and just drained the oil and changed the filter.
Now if it concerns you.....pull the pan and check rod/main bearings......
But the metal will HAVE to get sucked up through the oil pump and get pushed through the oiling system for it to do damage. It is possible but in experience not likely.
If you do pull the pan.....pull the oil pump and disassemble it first.....if it has BAD scoring on the gears then check your bearings......
After you put it back together.....stick a Rare Earth magnet on the bottom of the pan.....this will pull small metal particles toward it in the future...anything residual.

The springs are stock with 110 seat pressure that is what the cam called for. Half turn pre load. Been building motors for over 30 years and never seen a cam wipe out that fast ,cam company will not stand behind there product they all say you must have done something wrong , easy out for them .

What brand were the cam/lifters? Hard to get anything with quality in FT stuff these days. Usually the lazy ramp stuff has the best chance for survival
Did you take the inner spring/dampner off when you broke them in?
